7 Signs that Your Vision Is In Poor Condition
More Lights Left On Because Low Light Feels Like No Light

Are you angling your reading light to put more light on your side of the bed? Turning on your over-the-counter lights in the kitchen even when you're cooking during the day? Chance are, it's a sign that your vision isn't doing so well. When you're in need of an eye exam, you'll find yourself trying to compensate for blurred vision by adding extra illumination. Dimness decreases your ability to see what's happening in front of you, so you'll turn up the light in an attempt to make it better. Unfortunately, this won't help as much as you like. Pay careful attention to the amount of light you need in order to accomplish normal tasks. If it increases suddenly, it's time to have your eyes checked.
You Are More Clumsy Than Usual

You might not be the most graceful individual anyway. Perhaps you frequently find yourself tripping over your own feet or failing to notice that there's something in your path, especially if it's something small. You may also discover that you have trouble eating neatly, dropping more food on your clothing, or spilling more often. A few unexplained bruises or a brief episode of extra clumsiness probably aren't too bad. If it's getting increasingly frequent, however, your failing vision might be to blame! Won't it be nice to have an excuse that you can share with your friends? "Of course I'm not really that clumsy. I just needed to have my glasses prescription updated, that's all."
In senior adults, this clumsiness may manifest a little differently. Elderly individuals who are suddenly having more trouble seeing may stick closer to the walls, even running their hands along them as they walk to help make sure they stay on course. They may also shuffle their feet to help decrease the possibility that they'll miss something in the path.
